Bad connection at the harness RCA will produce a different kind of noise, "scratching", pops, low volume level or simply no sound at that particular RCA/speaker output.

Tried all still same!! Checked The RCA cables all cable is sutring where they should be, still scarathing noice and hissing and sub passenger side blaffering like flop floooop
